Question

Solve this: (ii) A jet plane is travelling towards west at a speed of 1800 km/h. What is the voltage difference developed between the ends of the wing having a span of 25 m, if the earth's magnetic field at the location has magnitude of 5 $\times$10^-4 T and the dip angle is 30 $°$ ?

Answer 1

Dear Student,

$$\begin{gathered} verticalcomponentofthemagneticfieldB\text{'}=B\sin \delta =5*{10}^{-4}*\sin 30=2.5*{10}^{-4}T. \\ speedv=1800*\frac{5}{18}=500m/s \\ lengthl=25m \\ inducedEMFE=B\text{'}vl=2.5*{10}^{-4}*500*25=3.125volt. \\ Regards \end{gathered}$$
